OVEN-DOOR.

SiPECIFICATIONforming part of LettersPatent No. 656,839, dated August 28, 1900.

Application filed J'unfi 20 1898. Serial No. 684,028- (No model.)

To aZZ whom izimay concern:

Be it known that we, FRANK EBERHAR'I and CHARLES AUGUST SGH'UBERT, of New York city, New York, have invented a new and useful Improvement in Oven-Doors, of which the following is a specification.

Our invention relates to bakers ovens, and has for one object to provide means whereby moisture may be imparted to the heated air within the baking-chamber.

Another object is to provide improved means for mounting a sight upon the front wall of the oven, and by the manipulation of which moisture collecting upon the same from the oven-chamber may be readily removed. To this end the invention consists, substantially, in the construction, combination, and arrangement of parts, as Will be hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a front view of the oven with the front plate removed. Fig. 2 is a front elevation of the front plate removed and showing our improved sight. Fig. 3 is a top View of the handle of the oven-door. Fig. 4 is a transverse section of the front part of the oven, showing the upper steam-chamber.

Referring to the drawings, A designates a horizontally-swinging door provided with a central balancing-Weight B, secured to one end of the fulcrum-rod E of the door and held thereon by means of a rod D, fitted in a central vertical opening in the weight 13, and which rod is provided with a socket at its lower end to receive the fulcrum-rod E. This weight is further provided with outwardlyprojecting lips having sockets X and X to receive a handle 0. When the handle is grasped and pulled forward, the counterbalancing- Weight B equalizes the weight of the door, and hence only a slight pull to open the door is necessary.

Located at one side of the door A is a steamseparating chamber F, into which steam is admitted through the pipe Q. The purpose of this chamber F is to separate the moisture from the steam, the water of condensation being removed through the pipe H, while the of the oven, where it is distributed into the upper portion of the oven-chamber through the openings in the rear or inner wall of the chamber L. These pipes G and R are of unequal length, one entering the chamber near its end, while the other extends farther into the central part of the chamber, thereby distributing the steam through the entire space of chamber L.

A plate T, having bolt-holes T, is secured to the front of the oven and covers the upper front edge of the baking-chamber, as shown in Fig. 4:, and is placed between the chamber L and the top edge of the door. This plate T is further provided with a longitudinal dovetailed groove T, into which is fitted a cor respondingly-shaped slide 0, carrying a transparent sight J. Near one end of the groove Tis an opening S, of the same size and shape as the sight J, and to one side of said opening is embedded a filling of asbestos cloth K, which serves as a wiper for the sight J. When the view through the sight is obstructed by the collection of moisture upon the inner face of the same, the slide 0 is drawn to the position shown in Fig. 2, and when returned to its normal position, which is when the sight J alines with the opening S, it has been freed of the moisture by the wiper K.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. In an oven,the combination with a steamseparator located at one side of the oven-door, of a distributing-chamber above the ovendoor, and having a series of perforations through which the steam is discharged to the ovenchamber, of steamconducting pipes communicating with the two chambers, one of said pipes discharging near the center of the chamber, and the other near its end, whereby the entire chamber is filled with steam before the steam enters the oven.

2. In an oven, the front wall of which is provided With an opening extending into the oven, combined with a sliding sight, and

means for cleaning such sight, substantially normal position and contacting with the wiper as dezeribed. when reciprocated in the slot.

3. n oven provided with a front plate having a groove, and an opening, and a Wiper 5 embedded within the groove at one end of the opening, combined With a bar sliding in Witnesses:

the groove and carrying a sight, said sight BERNHARD A. BUGE, adapted to aline with the opening when ina 7 CHARLES EBERHART.
